SteamOS Beta, a Debian-based distribution developed by Valve to be used in its hybrid PC / console, has just received a new update.Valve has two branches for SteamOS. One is a stable version (sort of) and the other one is a Beta. As you might expect, the developers implement big changes into the development branch first, and later into the stable one.
According to the changelog, additional packages have been added to the repo to support gdb, NFS, and to help in creating an alchemist chroot, and all the firmware packages are now pre-installed in order to enable support for more wireless network adapters.
Also, a steamos-updatelevel dummy package has been added, and the e2fsprogs, iptables, libdrm, debootstrap, initramfs-tools, curl, libav, and eglibc packages have been updated in order to implement the latest Debian fixes.
Check the official announcement for more details about this release. You can download SteamOS right now from Softpedia.
Remember that this is a development version and it should NOT be installed on production machines. It is intended for testing purposes only.
